Taken my paltry M83 data as far as I can - it's 30 minutes on target with a 4" fluorite refractor and an SXVR-M25C CCD, and obviously needs a lot more data (since the other GX's in the field aren't showing very well yet). Hopefully improved it over my previous data processing.
Larger / better quality:

I know the 2 GX below M83 (boxed anyway), but what are the 2 out-layers to the left? I cannot find my atlas at the present (after regretfully cleaning up my man cave / garage) (BAD jpeg, I know, but you get the idea)
Thanks.
